Morse Decoder Pro for Android

11 things about Morse Decoder Pro

1. Decoding parameters that can be manually adjusted include the audio frequency of an optional narrow-band DSP filter, the WPM dot/dash speed used for detecting characters, the threshold level of background noise, and whether Farnsworth timing is to be used for detecting spaces between individual characters.

2. In addition to the features of the regular HotPaw Morse Code Decoder, this Pro vesion of the HotPaw Morse Code Decoder also includes a RePlay function, which pauses recording and re-decodes tha previous 1 minute of audio input using the current manual settings.

3. The HotPaw Morse Code Decoder takes audio input from the microphone or headset input on your iPhone or iPad, decodes Morse Code, and displays the results in text form.

4. The Morse Code Decoder includes a built-in spectrogram to help determine the audio frequency of the Morse Code tones.

5. The Morse code WPM (words per minute) detection speed is automatically adaptive from about 8 to 40 WPM, and can be locked to the current estimated WPM dot speed (WPM lock icon locked).

6. Also, please use the manual settings if automatic decoding does not adjust to the frequency, WPM or background noise threshold level.

7. Please note that it is easy to mis-aim an iPhone's microphone so that its noise cancelling microphone will cancel out any Morse Code tones.

8. You can also manually set the WPM code speed using the plus and minus symbols that appear in the waveform graph, or the slider control on an iPad.

9. On the iPhone or iPod Touch, tap to the left of the waveform graph to switch the manual threshold slider on and off.

10. If the audio filter is enabled (frequency lock icon locked), it can be set for frequencies in the range of 400 to 1400 Hz.

11. A Histogram of the tone signal levels with a marker for the detection threshold level are displayed next to the waveform graph.
